Hi
> David I had use [EMAIL PROTECTED] for example of mail, is not real mail. > Peter I check same too, 53-255-112-92.pool.ukrtel.net don't resolve to A entry. But I suppose rnds option only check ip to fqdn. Is there a way to check only this ? I had see some ips marked as DENIED_RDNS_RESOLVE with same results, and belongs to ISP's. More examples: dsl88-226-48720.ttnet.net.tr host249.159.31.78.cable.morena.jarsat.pl This hosts belongs to customers who open a connection to send mail. Maybe must i move my customers to submission port ? I using spamdyke with plesk.
